CAN WASHER.

Application led October 15, 1923. Serial No. 668,789.

The object of this invention is to produce a comparatively simple and cheaply constructed means for washing and sterilizing milk cans.

A further object is to produce a device for this purpose which in addition to effectively washing and thoroughly sterilizing a milk can will likewise operate to reclaim milk and cream which may have been left in the can operated upon.

The invention further consists in the details of construction, combination and operative association of parts such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings: V

Figure 1 is a side elevation of the improvement, illustrating a milk can to be washed, arranged in the bowl thereof.

Figure 2 is a top lan view thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1. i

Figure 4 is an enlarged sectional view through the bowl and the nozzle carried thereby, and showing in the bowl the annular member which supports the milk can tops to be washed and sterilized.

As disclosed b the drawings I make use of a hollow stan ard which is supported on a suitable base 1. Preferably the base is of inverted bowl shape construction and the standard body includes a lower section 2 and an up er section 3. These sections have their con ronting ends threaded and are connected togethervby a coupling `4. The

spaces between the coupling and the confronting ends of the sections 3 and 4 provide a compartment for a packing 5 for snugly retaining a piston 6 in the upper section 3.

The piston cylinder comprising the upper standard section 3 has its upper end threaded for the reception of an inwardly threaded depending flange 7 on the lower face of the basin or bowl member 8 of the improvement. The bottom of the basin' is rounded inwardly toward the center thereof and the said center is thickened and provided with an opening for the reception of a tube 9. On the tube there is secured the body colpling 10 of the hot water injector nozzle. The nozzle proper, indicated by the numeral 12, being in the nature of a hollow perforated substantially globular member. The nozzle has its lower and open'edge flanged outward and is engaged by a bushing that is tted on the coupling 10. The tube 9 has the upper end of its bore beveled to provide a seat for a ball valve 14. The basin 8 has at its bottom an outlet opening surrounded by a short pipe 15 and through this pipe the Water, after acting on the interior ol the can 16 to wash and sterilize the same, finds an outlet. The can 16 as disclosed in. Figure 1 of the drawings has its mouth arranged in the basin 8 so that the nozzle will be received through the neck of the said can. As shown in Fig. 3, the holes in nozzle 12 extend from the central portion thereof to the top, so that the water sprayed through the nozzle will be rojected against substantially all parts op the interior of the can when the can is in the position shown in Fig. 1.

The annular flange or boss 7 provided upon the bottom of the basin 8 has screwed therein a pipe section 17 in which there is a casing 18 containing a check valve which will prevent water passing backward from 'the water chamber provided between the basin 8 and the portion of the cylindrical standard 3 above the piston 6 when the latter is in one position. Outward of the check valve 18 there is a stop cock 19. Preferably the pipe 17 is made up in connected sections and couplings, the same being of the ordinary character to provide water tight joints and the outer end of the said pipe extends into awater receptacle 20 whose bottom rests on a disk 21 secured tol a rod 22 which passes through a horizontall arranged support 24 which extends lateral y from and is removably and' adjustably secured to the lower standard section 2, said support being ad- 'ustable on rod 22 and secured thereto by a olt 23 and secured to the standard 2 by bolts 27. The central portion of the support. is provided with a semi-circular recess, and a clamp 25 whose body portion is less thany half the circle is arranged opposite the said center of the support. The clamp has outstanding arms and through these arms there is passed lock means 27 that engage the support and whereby the said support is eiectively sustained on the standard. B loosening said clamp the support 24 may ge raised o r lowered and the clamp again tightened to hold it in position.

The end of the pipe 17 which enters the water containing receptacle 20 is provided with a casing 28 in which there is arranged a check valve that prevents water passing directly from receptacle 2() through the pipe 17 into the cylinder above the piston 6, and also prevents water passing from thetank 20 back through pipe 35 of coil 34 and exerting a pressure back through said pipe and coil. i

Mounted on the support there is a suitable heater, which is broadly indicated by the numeral 30.

In the drum of the heater there is a cylindrical flue or chimney 31 that has its top wholly or partly closed and thatlias its bottom open to receive therein the burner 32 of the heater, a fuel tank 32 being shown below said burner. Leading from the bottom of the receptacle 20 there is a tube 33 which extends into the flue and which has its lower end terminating a suitable distance above the burner 32. The tube, from its straight lower end, is coiled as at 34 and has a straight upper branch 35 that passes through the heater and is connected by a coupling 36 to the pipe 17. In this manner it will be noted that the water from the tank or chamber 20 will be directed through the tube 33 and its coiled portion 34 to the center chamber of the heater which I have referred to as a flue. The water will be thoroughly heated before the same is permitted to pass through the pi e 17 into the chamber provided by the top o the cylindrical standard section 4.

Connected by a wrist pin 35 to the bottom of the iston 6 there is a link 36 that extends throng the standard into the hollow base thereof. Pivotally connected to the lower end of link 36, as at 37, is a foot pedal 3S that passes through a suitable opening in the base 1. The pedal 38 is pivoted, as at `39, between lugs 40 formed on the base at the opposite sides of the said opening in said base.

Firmly secured on the standard section 2, below the coupling there is a collar 41- Pivoted to these collars at 42, there is a lever 43. Pivotally connecting lever 43 to the pedal 38 there is a rod or link 44. llVhen an upward pull is exerted on the lever 43 the piston 6 will be moved downwardly in its cylinder provided by the upper standard sectlon so that a quantity of boiling water will be let into the `said cylinder above the piston.

The pressure of the operators foot on the outer -end of the pedal 38 will swing the latter to cause the link to move the iston 6 in an upward direction, thus forcmg the water through the recticulate nozzle against all parts of the can to thoroughly wash and sterilize the same. A single operation as above described has been found from experience ample to thoroughly clean and sterilize a milk can and when the caps or covers therefor are to be 4likewise washed andV sterilized, I arrange in the basin 8 a ringlike member 45 which provides a rest for the cover 46. The water as previously stated finds an outlet through the downwardly directed spout l5 on the bottom of the basin.

On the support 24 at the opposite side of the portion thereof on which the heater is supported there is pivotally mounted as at 4T a disk or plate 48. Resting on the plate at the opposite sides of the bars there are and milk will drain into can 51 before the f; i

washing and sterilizing process. Cans containing such milk and cream are not permitted to receive a full quantity of the boilv innr water through the nozzle but only a sufficient amount to drain the milk and cream from the walls thereof so that the full quantity of cream is received in the said can 5l. I then revolve the table 48 to bring the can 5() to the spout 15 and again operate the lever and pedal to inject into the can a full quantity of the boiling water so that the can is effectively cleaned, and the residue therefrom together with the used hot water,

is directed from the basin into can 50. By having the two cans 50 and 5l, it is not necessary to receive all of the rinse water in one can. The water that is used in the latter portion of the cleaning operation which contains little or no milk or cream, is not mixed with the water that is used in the initial cleaning and which is mixed with the residue of milk or cream. The residue of milk or cream in the can is thus saved and at the same time the amount of the rinse water which is shipped with the milk or cream is greatly reduced. A great saving is thus made in transportation charges on the milk and cream. Of course a sufficient amount of water will be received with the cream in the can 51, but the cream being of a lighter body will rise to the surface of the water. After a sufficient length of time the cock 52 can he opened to allow the drainin ofthe Water l from the can and upon the first appearance of cream through the faucet the latter is turned ott, and inthis manner I reclaim a comparatively large quantity of cream which is ordinarily wasted.

It is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction, advantages and operation of the improvement to those skilled in the art to which this invention relates, but I reserve the right, to make all such changes therefrom as fall within the scope of what I claim.
